置信区间

The shortest confidence interval of parameter of Gamma distribution is in practice a question of conditional extremum. It can be transferred to a group of equations that can be solved by a method of numerical value.

Γ分布中未知参数θ的最短置信区间实际上是一个条件极值问题，它能转化成一个方程组可用数值方法迭代求解。

Note, this property applies in general to confidence interval p values, not just this problem and this test statistic Z.

注意，这个特性普遍存在于置信区间P值，不止在这个问题和这个测试统计量Z。

Confidence intervals were measured and reported. Norms obtained using the CHINT and MHINT are comparable to those for the English HINT.

As is eident from the 95% confidence interal around the point estimate, the data are consistent with as much as a 7% decrease in cardioascular risk and as much as a 32% increase in risk.

鉴于95%的置信区间，这一数据就意味着心血管疾病发病风险降低7%和增加32%。

Some example results show that it is consistent with current formular.So it not only provides an index for assessing the accuracy of line and polygon but also give a formular which can determine the size of confidence...

这不仅为GIS中线、面的精度评定提供了一个指标，而且为任意p维随机向量在不同置信度下、置信区间大小的确定提供了一个通用公式

The L10 and L50 life of the treated specimens increase by 99.6% and 236.3% at a Hertzian stress of 5.1GPa and 90% confidence level, respectively.

在赫兹接触应力为5.1GPa，90%置信区间下的L10和L50寿命分别增加了99.6%和236.3%。

we carry on logistics demand forecast by taking time-series model and explain its application to logistics demand forecast by justment of data stationary, stead, standardization, modeling, discernment, making steps, parameter estimate and examination to predict, error and calculation of confidential interval.

本文采用时间序列模型进行物流需求预测，用实例从数据平稳性的判断，平稳化，标准化，建模，经模型的识别、定阶、参数估计和检验，到预测及误差和置信区间的计算，详细地说明了时间序列模型在物流需求预测中是如何应用的。

Data for 4,228 cases and 84,540 controls matched on age and follow-up time were analyzed by using conditional logistic regression, adjusted for sex, age, health status, health care utilization measures, exposure to contrast agents, and nephrotoxic medications.

对于所有的服用NSAIDs者而言，在30天之内开始治疗，其发生急性肾衰竭的危险性最高（调整率比=2.05，95%置信区间：1.61，2.60）。

The big advantage of the Jackknife is that they can be used to evaluate the statistical properties of a statistic that is related to the data in a complicated, nonanalytical way. Apart from estimation of standard deviation, Jackknife can be used to estimate mean, median and even to construct confidence intervals.

大折刀法的最大优点是它能在一个统计量与资料的关系很复杂或无解析的表达式时，可用它估计统计量的统计特性，除了能得到标准偏差外，还可用来估计平均值和中值，甚至构造置信区间。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
